Diagnosis. Recognized by its generally pale green, moderate-sized, elongate, subparallel-sided body ( Fig. 5J– K ); darkened apex of clypeus ( Fig. 5L ); narrow brown macula at apex of corium; reddish brown apical 1/2–1/3 of metafemur; projected phallotheca with a subapical fold ( Fig. 20O ); and narrow, spatulate vesical ventral sclerite with a small, hooked process at apex ( Fig. 20O ). A combination of these characters enables this new species to be distinguished from other Asian congeners. Description. Body elongate-oval, subparallel-sided, moderate in size; basic coloration pale green; dorsal surface with uniformly distributed, pale, simple, short, reclining-semierect setae. Head pale brown, weakly tinged with red, shining; basal transverse carina of vertex slightly narrower than pronotal collar. Antenna pale brown; apex of segment II, entire III and IV brown. Labium pale reddish brown, slightly exceeding apex of mesocoxa, shorter than metafemur; apex of segment IV darkened. Pronotum and scutellum shining, partly tinged with red; thoracic pleura pale reddish brown; scent efferent system pale brown, subtriangular with small peritreme ( Fig. 20H ). Hemelytra shiny pale green; clavus more or less tinged with brown; apex of corium with a brown, narrow macula; membrane smoky brown, speckled with semitransparent, pale portions. All coxae creamy pale brown; legs pale brown; basal 1/2–1/3 of metafemur reddish brown ( Fig. 5L ); apex of each tarsomere III darkened; meta-tarsomere II slightly longer than III ( Fig. 20I ); pretarsal structure as in Fig. 20J ; parempodia relatively short. Ventral side of abdomen yellowish green. Male genitalia ( Figs. 12A–C , 20K–O ): Sensory lobes of parameres moderately produced at apex ( Figs. 12A– B , 20L–N ); right paramere with hooked hypophysis ( Fig. 12B , 20N ); vesica with weakly curved spiculum and spatulate, narrow ventral sclerite ( Figs. 12C , 20O ). Female genitalia: Not examined. Measurements : See Table 1 . Etymology. From Latin, rufi- (rufus, red) combined with femoratus (= femur), referring to the reddish femora of this new species; an adjective. Distribution . Taiwan ( Taichung ). Biology. Unknown.
